Combined surface x-ray diffraction and density functional theory study of the germanene/Al(111)-(7×7) R19.1° structure

K. Zhang, M.C. Hanf, D. Sciacca, Romain Bernard, Yves Borensztein, A. Resta, Yves Garreau, A. Vlad, A. Coati, Isabelle Lefebvre, M. Derivaz, C. Pirri, P. Sonnet, R. Stephan, G. Prévot

Several studies have reported the possible growth of germanene on various metal surfaces. However, the exact structure of the layers formed upon evaporation at or above room temperature remains controversial. In particular, the layers obtained after Ge deposition on Al(111) have been either…

High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems

Mohammad Alibakhshikenari, Bal Virdee, Dion Mariyanayagam, Valeria Vadalà, Mohammad Naser-Moghadasi, Chan See, Iyad Dayoub, Sonia Aïssa, Patrizia Livreri, Shah Nawaz Burokur, Anna Pietrenko-Dabrowska, Francisco Falcone, Slawomir Koziel, Ernesto Limiti

An innovative off-chip antenna (OCA) is presented that exhibits high gain and efficiency performance at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented on stacked silicon layers and consists of an open circuit meandering line. It is shown that by…

Monolayer molybdenum disulfide switches for 6G communication systems

Myungsoo Kim, Guillaume Ducournau, Simon Skrzypczak, Sung Jin Yang, Pascal Szriftgiser, Nicolas Wainstein, Keren Stern, Henri Happy, Eilam Yalon, Emiliano Pallecchi, Deji Akinwande

Atomically thin two-dimensional materials—including transitional metal dichalcogenides and hexagonal boron nitride—can exhibit non-volatile resistive switching. This switching behaviour could be used to create analogue switches for use in high-frequency communication, but has so far been limited to…

How to tame a free non-laminar Savart sheet into individual jets?

Sofiene Oulded Taled Salah, Ghada Chouk, Alexis Duchesne, Nicolas de Cock, Khaoula Abrougui, Frédéric Lebeau, Stéphane Dorbolo

In this article, we study the division of a non-laminar Savart sheet into individual jets by mean of local disturbances. We paint a precise portrait of a free non-laminar Savart sheet formed by the vertical impact of a jet on a horizontal disk, its evolution in the air and its break up. We then…

Load-Pull Setup Development at 185 GHz for On-Wafer Characterization of SiGe HBT in BiCMOS 55 nm Technology

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Marc Margalef-Rovira, Issa Alaji, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article aims to discuss challenges and performances of a passive load-pull test bench dedicated to the G-band frequencies. The first task of this work is the development of the setup to perform high power generation, impedance generation, and high-power dynamic of measurement. The solution…
